What is one disadvantage of using wind energy rather than burning coal to produce electricity a: the power it produces is economical b: wind energy can be converted directly into electricity c: the turbines are too large d: it does not cause pollution?

C) The turbines are too large

Step-by-step explanation:

The question is what is the disadvantage of wind energy over burning coal.  A) is not a disadvantage B) is not a disadvantage D) is not a disadvantage, however, C) is a disadvantage.

Wind power, where suitable amount of wind is available, is economical, it can be converted directly into energy and does not cause any pollution.  These are all advantages over burning coal.  However, turbines are large, and depending on the amount of electricity needed, can require large amounts of space and or land to accommodate the number of turbines needed

Coal, is not a renewable resource making it a limited supply which makes it less economical and sustainable.  It has to be burned in order to generate and be turned into electricity, which causes pollution.

The only disadvantage to wind energy is that the turbines are very large and require a large amount of space in order to collect enough kinetic energy to convert to electrical

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
